Cohen's Kappa

Cohens Kappa,

Definition of Cohens Kappa:

  1. A way of measuring agreement in statistical treatments of qualitative data, such as customer satisfaction surveys, that is intended to reduce the effect of coincidental agreement that is sometimes observed with percent-agreement calculations. Use of this coefficient is considered a more conservative approach, in that it risks understating rather than overstating agreement between data points.
